The hearing had the hallmarks of the intentionally or naively blind leading the blind with political shamelessness.

From time to time the discussion turned to the absence of a legal "predicate" to investigate President Donald Trump for colluding with Russia. That is, of course, important; and we can expect to hear a lot more about that in coming months.

More important: what remains unacknowledged is the absence of an evidence-based major premise that should have been in place to anchor the rhetoric and accusations about Russia-gate over the past three years. With a lack of evidence sufficient to support a major premise, any syllogism falls of its own weight.
